I got so bad with short-term memory, focus and word-finding that I thought I was developing dementia. However, two different psychiatrists have told me that my brain-fade is due to repeated severe bipolar episodes combined with medications (e.g. Lamictal and antipsychotics). That made me feel better because it's not unheard-of to get dementia at my age, but then it's not modifiable either because I can't get rid of bipolar and I can't stop taking meds. Oh well.
